, Be it known that 1, Gnonen iP-ArrANi- KoLAoU, a subject of the King: of Greece, iresiding at Petersburg, in the county of'Dinwiddie' and. State of Virginia, have invented certain new and useful Improvements In Smoke Cleaners; and I do hereby declare the following to'be a full, clear, and exact description of the inventionysuch as Wlll enable others skilled inrthel art to which-it appertains to make andtuse thersame.

l This invention relates to 'improvements in smoke cleaners or filters and 1t 1s part1cu-' larly designed ior iuse in connection with the smoke exit pipe or smoke stack of railway locomotives. j j Y I One of the objects of my invention is to provide a smoke cleaner capable of attachment to an ordinary smoke stack without altering or changing the construction of the Another object of the invention is to provide a liquid container and means combined with the smoke stack, for directing the smoke into the liquid, after leaving said stack.

A further object of theinvention, is to furnish a smoke filter having means for readily cleaning the same without removing the device from the smoke stack.

A still further object, is to provide a smoke cleaner with means for automatically removing some of the collected matter.

With the foregoing objects outlined and with other objects in view, which will appear as the description proceeds, the invention consists in the, novel features hereinafter described in detail, illustrated in the accompanying'drawing and more particu larly pointed out in theappended claims.

Referring to the drawing: 1.

Fig. 1 is a vertical transverse sectional View of a locomotive smoke stack and my improvements applied thereto.

Fig. 2 is a horizontal sectional view of the same, taken on line 22 of Fig. 1.

In the drawing, 1 represents an ordinary locomotive smoke stack, which is enclosed by a liquid containing casing or housing 2, having an open upper end 3 to permit the exit of the smoke and a curved bottom 4 conforming to the curvature of the top of the locomotive boiler. As shown in Fig. 2,

" the side. wall of the casing is elliptical in shape in order to rest on the boiler without Specification'of Letters' Patent. r

-,E xtending into, v the stack 1, is -a cone; 5 having its upper end-pfiared downwardlyin which. acts-to deflect ---the. ismoke from the stack downwardly. into the :liquid, contained within the casingQ. Elie part 6 is supported by t-1e-v members "7, which are a-rrangedibetween the member 6-.andfthe dome-8, ands sa1d -domeiswcarriedby-?supporting-zlegs 9- i -wh-1ch extend upwardlyfnom'rthe-rbottom i ot the casing. The:v domeffunctions was a cover for the cone 5-. Surrounding the lower portion of the dome 8 and extending, beneath the surface of the liquid'in the easing 2, is a mufi or sleeve 10 carried by supporting legs 11 and braced by upwardly ex.- tending brackets 12. causes smoke issuing from 'thestack to pass downwardly beneath the surface of the wa a bell shaped manner, to ,provide z-a'baflie 1-6 i This muff or sleeve ter before passing to the outlet 3, and it... w1ll beunderstoodthat smoke issuing from,

the stack will be ordinarily propelled with such force as to pass through the liquid rather than between the lower edge ofthe dome and the inner wall of the .mufl or sleeve. If desired, however, thelower edge of the part (Sand the dome 8 canbeextended downwardly flush with the lower edge of the mufi' or sleeve 10.

The side walls of the casing 2- are provided with outlet openings 14:- arranged justabove the normal level ofthe liquid in the casing and as the dirt, ashes, dust, etc., ac

cumulate in the liquid, a portion of the same will automatically overflow with the water and pass out through said openings.

The lower portion of thecasing is provided .with valved clean-out pipes 15 and like carried by the smoke, will be deposited" in the liquid, while the cleaned or filtered smoke will rise, from the water and pass off through the outlet 3. 7 e

I am aware that various changes and the upper portion of the casing has water 1 modifications may be made in the construction illustrated, without departing from the spirit of the invention or sacrificing any of itsadvantages.

What I claim and desire to secure 'byLet ters Patent is .The combination with a smoke stack,

of a cone having its apex extending into the stack to a point near its lower extremity, and the base of the cone being flared and forming a bafllearound the upper portion of the stack, the sides of the cone "forming with the sides ofthe stack, a passage of gradually decreasing diameter for the outgoing products of combustion, thereby increasing the velocity; of movement of the same, a sleeve or mufl' surrounding the base of the cone and a liquid receptacle enclosing the stacki and muff, the lower edge of said mufl' extending beneath the surface of the liquid contained in'the receptaele 2. The combination with a smoke stack,

of a cone having its apex extending such a distance within the stack as to provide'bef of the stack,

from the upper portion of the muff to said casing, the lower edge of the muff extending below the liquid level of the casing and a smoke outlet for said receptacle.

3. The combination as defined in claim 2, in which the 'bottom of the qreceptacle is curved to conformwith the upper surface of alocomotive boiler. T v p 4 1 1 In testimony whereof I affix my signature.
